Front

What does it mean if two lines are parallel when graphing a system of equations?

Back

It means there is no solution to the system, as the lines never intersect.

Front

How can you determine if an ordered pair is a solution to a system of equations?

Back

Substitute the values of the ordered pair into both equations; if both equations are true, it is a solution.

Front

What is a nonlinear system of equations?

Back

A system that includes at least one equation that is not linear, such as quadratic or exponential equations.

Front

What does it mean if a system of equations has infinitely many solutions?

Back

The equations represent the same line, meaning every point on the line is a solution.
